SUMMARY:

The growth of the urbanization process that has occurred in the last decades has caused an increase in civil construction and, consequently, an increase in the generation of waste arising from this process. The waste from construction and demolition of civil works (CDW) represents the majority of the volume of waste that is generated in large urban centers, and it is necessary that an appropriate destination be carried out to mitigate the environmental impacts and the social problems they cause. Based on these factors, several researches were carried out in different
regions of Brazil and the world in order to use this residue as an alternative material in paving works. In this context, this work aims to analyze the use of CDW associated with different types of soil from the state of Rio Grande do Norte, aiming at its use in paving works. For this, the percentages of CDW of 25%, 50% and 75%, by mass, were added to the soil, in order to verify the benefit that this increase can cause in the characteristics of the materials. The experimental program was carried out using CDW samples obtained by a private company, and soil samples extracted from three major regions in the state of Rio Grande do Norte. The laboratory investigation methods were based on physical characterization, compaction, CBR and grain break analysis tests. The results obtained show that depending on the percentage of residue and the type of soil, the increase of CDW to the soil causes the CBR values to rise and improve the properties of the samples. Thus, the replacement of part of the natural aggregate by CDW is a potential alternative for application in pavement works.
